Symantec Messaging Gateway version 9.5.3-3 suffers from backdoor account and privilege escalation vulnerabilities.
e1a9b2ba54c980d0ecd312d2a5ed1672VMware Security Advisory 2011-0012 - VMware ESXi and ESX updates to third party libraries and ESX Service Console address several security issues.
09895b515d192ac17d0b7edd6177d76bUbuntu Security Notice 1202-1 - Dan Rosenberg discovered that several network ioctls did not clear kernel memory correctly. A local user could exploit this to read kernel stack memory, leading to a loss of privacy. Brad Spengler discovered that stack memory for new a process was not correctly calculated. A local attacker could exploit this to crash the system, leading to a denial of service. Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. Various other issues were also addressed.
2daff38dec5e5b4254f2f5b46b1f6f9eThis exploit leverages three vulnerabilities to escalate privileges. The primary vulnerability is a kernel stack overflow, not a stack buffer overflow as the CVE description incorrectly states. This may be the first public exploit for a kernel stack overflow, and it turns out to be a bit tricky due to some particulars of the econet vulnerability. It involves the econet_sendmsg function, ec_dev_ioctl function, and the ipc subsystem. Linux kernel versions prior to 2.6.36.2 are affected.
bd4bed020aee338cfb73fae11991a04aUbuntu Security Notice 1186-1 - Dan Rosenberg discovered that IPC structures were not correctly initialized on 64bit systems. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Steve Chen discovered that setsockopt did not correctly check MSS values. A local attacker could make a specially crafted socket call to crash the system, leading to a denial of service. Vladymyr Denysov discovered that Xen virtual CD-ROM devices were not handled correctly. A local attacker in a guest could make crafted blkback requests that would crash the host, leading to a denial of service. Various other issues were also addressed.
c5e74b8176fba1d422fe47aa4c8e7658Mandriva Linux Security Advisory 2011-051 - The Linux 2.6 kernel has been updated to mitigate multiple vulnerabilities related to denial of service, arbitrary code execution, stack memory disclosure, restriction bypass, and more.
f2ce03c37e6b21cbf22fe118915e6000Mandriva Linux Security Advisory 2011-029 - Multiple vulnerabilities have been discovered and fixed in the Linux 2.6 kernel. The X.25 implementation does not properly parse facilities, which allows remote attackers to cause a denial of service (heap memory corruption and panic) or possibly have unspecified other impact via malformed data, a different vulnerability than CVE-2010-4164. The bcm_connect function Broadcast Manager in the Controller Area Network implementation in the Linux creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename. The install_special_mapping function in mm/mmap.c does not make an expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application. Various other issues have also been addressed.
b09673d46bd0c26aeac9afa523e5a306Debian Linux Security Advisory 2126-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak.
